   Service Brakes, Air / Antilock / ABS Warning Light

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

   Consequence, in the NHTSA record

   If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

   Remedy, in the NHTSA record

   PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 20pbc AND 20KWB. Owner notification date in the NHTSA record: 26 May 2020.

2. 11V203000Received 24 Mar 2011. 5,831 units.

   Engine and Engine Cooling

   Defect, in the NHTSA record

   Paccar is recalling certain model year 2007-2011 kenworth c500, t2000, t600, and t660, as well as model year 2009-2011 peterbilt 387 and 388 trucks equipped with caterpillar c15 engine and manufactured from may 11, 2006, through september 17, 2010. Degradation of a combustion tube weld can cause radial heat impingement on the body which may burn through certain bodies used on c15 engines.

   Consequence, in the NHTSA record

   This could result in a fire.

   Remedy, in the NHTSA record

   Caterpillar is handling the owner notification and remedy for this campaign. Please see caterpillar's defect report 11e-006. Caterpillar will replace the single piece combustion tube with a thick wall combustion tube which will not allow the heat to break through. This service will be performed free of charge. Due to a parts supply issue, owners will be notified by the end of april 2011 about the safety defect, and will then be notified again once the free remedy is available, currently estimated to be around late july 2011. Owners may contact caterpillar toll-free at 1-800-447-4986.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 11KWB & 0311-A. Owner notification date in the NHTSA record: 4 Aug 2011.

3. 11V127000Received 23 Feb 2011. 4,664 units.

   Fuel System, Other / Storage / Tank Assembly

   Defect, in the NHTSA record

   Paccar is recalling certain model year 2008-2012 kenworth t2000, t660, t700, t800, and w900, as well as model year 2009-2012 peterbilt 365, 367, 384, 386, 387, 388, 389, and 587 trucks equipped with paccar mx engines. The oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.

   Consequence, in the NHTSA record

   The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.

   Remedy, in the NHTSA record

   Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap. This service will be performed free of charge. The safety recall is expected to begin during march 2011. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number E026R. Owner notification date in the NHTSA record: 4 Mar 2011.

4. 10V634000Received 13 Dec 2010. 12,873 units.

   Power Train / Axle Assembly

   Defect, in the NHTSA record

   Paccar is recalling certain model year 2007-2008 kenworth and peterbilt vehicles manufactured from february 2, 2006 through april 30, 2007. The bearing surfaces of the extended lube universal joint that attaches the inter-axle driveline to the drive axle may become prematurely worn due to breakdown of lubrication and/or excessive heat. Prematurely worn bearing surfaces may result in the u-joint becoming loose and/or binding. This condition may result in universal joint failure, allowing the inter-axle driveline to detach from the axle.

   Consequence, in the NHTSA record

   Detachment of the driveline from the axle may cause the vehicle to lose power and become disabled in the roadway. Also, the driveline could drop from the vehicle into the roadway increasing the risk of a crash.

   Remedy, in the NHTSA record

   Paccar is working with its supplier to remedy the vehicles free of charge. The safety recall is expected to begin during february 2011. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number K-10KWL P-1201F. Owner notification date in the NHTSA record: 4 Mar 2011.

5. 10V308000Received 2 Jul 2010. 9,697 units.

   Steering / Column

   Defect, in the NHTSA record

   Paccar is recalling certain model year 2008-2010 trucks equipped with trw steering shafts. The circumferential weld around the steering shaft tube that welds the splined tube to the non-splined tube may be mislocated. Mislocation of the circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.

   Consequence, in the NHTSA record

   A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash.

   Remedy, in the NHTSA record

   Dealers will inspect the steering shaft using a weld placement gauge provided by trw. Any steering shaft found to have been welded improperly will be replaced free of charge. The safety recall began on july 30, 2010. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KW-F & 0610-D. Owner notification date in the NHTSA record: 30 Jul 2010.

6. 09V239000Received 30 Jun 2009. 3,423 units.

   Service Brakes, Air

   Defect, in the NHTSA record

   Kenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. Increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components.

   Consequence, in the NHTSA record

   Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.

   Remedy, in the NHTSA record

   Dealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. The recall is expected to begin or before july 25, 2009. Owner may contact kenworth at 1-425-828-5440.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW7. Owner notification date in the NHTSA record: 20 Jul 2009.

7. 09V166000Received 19 May 2009. 140 units.

   Service Brakes, Air / Disc

   Defect, in the NHTSA record

   Paccar is recalling 140 my 2005, 2007-2009 t800, w900, and t660 trucks. The caliper mounting fasteners attaching the air disc brake caliper assembly to the torque plate may have received insufficient torque during the installation process. The insufficient torque may allow the air disc brake caliper assembly to become loose and possibly separate from the vehicle.

   Consequence, in the NHTSA record

   This could result in reduced braking capacity and also a road debris hazard, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will inspect air disc brake caliper assemblies and replace the caliper mounting fasteners and torque properly. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule. Owners may contact kenworth at 1-425-828-5440.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 09KW3. Owner notification date in the NHTSA record: 15 Jun 2009.

8. 08V485000Received 24 Sep 2008. 130 units.

   Suspension

   Defect, in the NHTSA record

   Paccar is recalling 130 my 2004-2009 t2000, t800, t600, w900 and t660 kenworth trucks built with an ag400 rear suspension, long stroke brake chambers, and wide base tires (super singles). These vehicles may develop an increase in lateral and vertical axle movement. This movement may cause part or parts of the brake assembly (brake cam tube support, brake chamber bracket, brake chamber, brake spider) to develop fatigue cracks, possibly resulting in the failure of the part or parts within the brake assembly.

   Consequence, in the NHTSA record

   A failure may reduce vehicle brake performance, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will install the cam tube support brackets on all of the rear axle wheel ends. Inspect the rear axle brake assembly and replace it if cracked. The recall is expected to begin during november 2008. Owners may contact kenworth at 1-425-828-5440.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KWB. Owner notification date in the NHTSA record: 26 Jan 2009.

9. 08V487000Received 23 Sep 2008. 4,883 units.

   Engine and Engine Cooling / Engine / Diesel

   Defect, in the NHTSA record

   Paccar is recalling 4,883 my 2006-2009 kenworth t600, t660, t800, w900, t2000 and my 2008-2009 peterbilt 365, 367, 379, 384, 386, 387, 388 and 389 trucks. Inadequate stiffness of the diesel particulate filter (dpf) bracket could result in separation of the dpf from the chassis.

   Consequence, in the NHTSA record

   A vehicle crash could occur if another vehicle strikes the dpf on the roadway.

   Remedy, in the NHTSA record

   Paccar is working with caterpillar to repair these vehicles (please see 08e041). Owners may contact caterpillar at 1-800-447-4986 or kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KWD 908G.

10. 08V128000Received 21 Mar 2008. 1,043 units.

    Parking Brake / Conventional / Air

    Defect, in the NHTSA record

    Paccar is recalling 1,043 my 2008-2009 kenworth c500, t2000,t660, t800 and w900 trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.

    Consequence, in the NHTSA record

    If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, causing reduced ability for modulating the service emergency brakes. In such an event, the operator should observe an air leak, indications of low air pressure via the primary and secondary air gauges, and audible and visual low air pressure warning alarms. A vehicle crash is possible if these warnings are not heeded.

    Remedy, in the NHTSA record

    Dealers will replace the bendix mv-3 dash control valves free of charge. The recall began on april 14, 2008. Owners may contact kenworth at 1-425-828-4196.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KW3 308E. Owner notification date in the NHTSA record: 14 Apr 2008.

11. 08V065000Received 7 Feb 2008. 6,169 units.

    Latches/Locks/Linkages / Doors / Latch

    Defect, in the NHTSA record

    Paccar is recalling 6,169 my 2008 kenworth t300, t660, t800, t2000, w900 and c500 vehicles and my 2008-2009 peterbilt models 365, 367, 384, 387, 388, 389 and 389 kits. Certain door latch assemblies on these vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 206, 'door locks and door retention components." the rotor in some of these door latch assemblies did not receive the proper heat treatment and may be soft.

    Consequence, in the NHTSA record

    In the event of a crash, force could cause the rotor to crack and the door would not have primary or secondary closing security which could possibly lead to injury of the vehicle occupant.

    Remedy, in the NHTSA record

    Paccar is working with trimark and will inspect and replace the door latch if it is found to be defective. The recall began on march 14, 2008. Owners may contact kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4196.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 08KW1/108A. Owner notification date in the NHTSA record: 14 Mar 2008.

12. 07V591000Received 20 Dec 2007. 559 units.

    Steering / Gear Box / Shaft Sector

    Defect, in the NHTSA record

    On certain kenworth and peterbilt heavy duty trucks equipped with tas-85 trw steering gears, the inner surface of the outer sector shaft teeth of the steering gears may have an incorrect involute profile, which may lead to chipping and damage of the gearing system.

    Consequence, in the NHTSA record

    This type of damage may cause a "bind/stick" condition in the vehicle steering during a turn increasing the risk of a crash.

    Remedy, in the NHTSA record

    Dealers will repair and replace any suspect tas-85 steering gear assembly free of charge. The recall began on january 9, 2008. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4201.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 07KWE & 1107K. Owner notification date in the NHTSA record: 9 Jan 2008.

13. 07V269000Received 26 Jun 2007. 9,571 units.

    Trailer Hitches

    Defect, in the NHTSA record

    On certain trucks, the removable tow hitch ,when used to tow or lift a vehicle, can fail due to defective material in the tow hitch.

    Consequence, in the NHTSA record

    If the tow hitch assembly fails while a vehicle is being towed or lifted, it may cause an accident that could result in personal injury or death.

    Remedy, in the NHTSA record

    Dealers will replace the tow pin assembly free of charge. The recall began on september 4, 2007. Owners may contact kenworth at 425-828-5440 or peterbilt at 940-591-4201.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 507E & 07KWA. Owner notification date in the NHTSA record: 4 Sep 2007.

14. 07V195000Received 7 May 2007. 111 units.

    Engine and Engine Cooling / Cooling System / Fan

    Defect, in the NHTSA record

    On certain trucks built with cummins c15 or isx engines and equipped with horton engine fans, durability testing revealed micro cracks in the fan blades.

    Consequence, in the NHTSA record

    The possibility exists that these micro cracks could develop into larger cracks which could cause the fan to break apart while turning resulting in equipment damage or physical injury.

    Remedy, in the NHTSA record

    Dealers will replace the fan blade assemblies free of charge. The recall began on june 22, 2007. Owners may contact kenworth at 425-828-5440.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 07KW7. Owner notification date in the NHTSA record: 22 Jun 2007.
